[en]: In 1992 I lived in Korea. The house had thin walls and my neighbour appreciated very much that I made a pencil drawing of my trumpet instead of playing it. That was my first "nature morte" ever. I simply drew what I saw - lying infront of me, not from a photo. - - Then I still didn't have a scanner. So I used my FAX machine to scan the picture. I lost the original. What you see here is the vectorized scan.

Bremsklötze niederwalzen!
The Merkel Roller unleashed. (Hand drawn and then vectorized)
Angela Merkel (now German chancellor) on how to deal with obstacles to growth (Kiel, Germany, 2005-06-12): Where there are road blocks, "we'll have to roll them down." (Wo es Bremsklötze gebe, "da müssen wir sie niederwalzen.") For that ambitious goal she surely needs powerful equipment.

Cartoons, 1981
Until 1982, I worked as a journalist for a weekly magazine for the electronics industry. I was in charge of the section for electronic measurement equipment and also made some cartoons for the magazine.

Handle Carefully
In 1989 my wife and I moved from Taipei to Seoul. In order to convince customs to handle the parcels carefully when opening them for inspection, I glued that little sketch on each parcel. It worked out nicely.

By the way: I did not manipulate any color hues.
32 Butterflies for a 16-port FFT
Fast Fourier Transform
The blue boxes do the elementary DFT (Discrete Fourier Transform). They also are called "decimation butterflies" and perform four operations: one complex multiplication, one sign inversion and two complex additions.
Usually the transformer is presented differently. This depiction of course does not change the design, but it shows the construction of the transformer using a fractal approach. In the usual presentations (of Radix-2 FFT algorithms), the butterflies cross the lines; in t…
